What you describe is likely to be "powdery mildew", a fungus disease. An advanced infection is difficult to control, and you will not be able to eradicate it from the infected foliage, but you can prevent further infection on new growth.

Light is limited to 4 hours direct in midday.
There are two separate flowers. Male, and female. Usually, the males will show long before female so that there will be pollen around. Females will show up, and have a small fruit on the bottom. Once they are pollinated they will swell into fruit.
Most of the time, this takes patience. Sometimes, if it is hot and dry out, then it will take a lot longer before you see female flowers. Once it is cool, and a little more humid, they will show up.
I have been reading the questions on the zucchini bumps, but the answers are always about while they are growing. Some of mine has been getting bumps AFTER I refrigerate them. They look beautiful when I pick them. I rinse them and put them in the fridge. The next day some will have weird little bumps.
A bad zucchini squash is easily identifiable as the skin appears dull and lifeless. Do not eat a zucchini if it is covered with rotten spots or decay. The vegetable may feel mushy, and the skin may be wrinkled or shriveled. If you cut into a bad zucchini, the inner flesh may be stringy and filled with large seeds. Zucchini goes bad once it has exceeded its shelf life or if it is stored improperly.

My garden has loads of flowers but minima veggies. I’ve had flowers for week but it’s not turning into zucchini, butternut squash and cucumbers. What could be wrong?
Watering is the first consideration: are you supplying enough to faciliate plant metabolism and fruiting.
Soil fertility and possible nutrient deficiencies are next to consider. Did you prepare the soil well with compost, mineral and biological amendments? Do you fertilize?

My seeds produced great plants but I am only getting flowers and no squash. Why?
No squash? In the champion pumpkin capital of the world? I suspect nutrient deficiency.
Soil fertility and water management should be your first concerns.
Water adequately and use a slow release, complete organic fertilizer like this:

Bought what I thought was a zucchini plant but it has morphed into what looks like a dark green butternut squash. Do you ha e any idea what this might be?
This is a zucchini. This can just happen sometimes when they need just a little more phosphorus and potassium. Make sure that soil is fertile, and does not contain too much nitrogen, or any slow release fertilizers. These will cause this symptom.
